SMT to DIP Adapters - WITH SOCKETS ???

Do not think you need a spot welder. Just apply solder paste to the IC pads, do the pick-and-place, then carefully put in an oven for reflow. If parts need to go on other side, make sure all small parts get reflowed on one side first, leaving the side with bigger parts ("squashed bugs" i call them) on top when reflow. The capillary action of the (liquid) solder on the "bottom" side is more than strong enough tohold small parts. I have a board that holds about 78 parts on both sides; the PCB is

0.5 by 1.4 including pads for wires. The only problems i have seen was due to one lead not being wetted during fab.

Hi, SMT by hand is easy and inexpensive when you know how. Not always just for robots:) And you don't need to buy expensive hot-air rework stations etc.

I put alot the technqiues for SMT hand soldering in my product at

There's a free membership there which has some of the videos.

Also, there's a nice article on low cost DIY hot air rework, written by Tom Mathews and Timothy Toroni at National Semiconductor. It's called "Rework within your reach"

Also, Schmartboard are trying to make it easier for prototyping with SMT chips. They have a bunch of different types, for SOP, QFP, PLCC, BGA etc. They fan out to through-hole pads, which you can solder wires or pins to & then connect off to your breadboard

You can do that with hot air[*], an oven, or Chip-Quik (a low-temp solder you flood on the pins). It's easy if you don't care about the device, though, just score the pins at the device and remove the pins by swiping your iron by with a blob of solder.

[*] or a propane torch on the back, followed by a whack on the bench. Wait, you said preserve the board?? ;-)
